What do we do?
Bespoke Business Development
We work with businesses in the UK, Ireland and US, remotely and in person, delivering education and development, so that their business has the right support to grow.
Every development project starts with a conversation. We take the time to understand what you want to achieve, identify any challenges and headaches you’re facing, and uncover skills gaps that may be holding your employees and business back. From there, we will create a clear bespoke course that will grow your business and assure you achieve all those goals you have in mind.
Our development programmes can range from intensive one-day courses through to comprehensive long-term development plans, ensuring your team members are working to their full potential in their current roles.
Where needed, development can be delivered remotely through interactive live video sessions and webinars, supported by carefully curated practical tasks, delivering our signature engaging education style. It’s as close as possible to being there in person, something we were leading the way in, long before virtual learning became the norm during Covid.
We deliver engaging training across many specialist subjects, including:
- Gemmology and gem testing
- Diamond identification, grading and valuation
- Valuation for pawnbroking
- Metals and precious metal testing
- Hallmarking
- Selling gemstones with confidence
- Selling diamonds effectively
- Induction training
- Customer experience
Courses and Events
It has always been at the heart of Gemmology Rocks to create a space where education is entertaining and engaging. We saw a gap in the market where there were no piles of textbooks and bored looking students. We have curated a wide variety of events, workshops and courses designed to make jewellery and gemstone education accessible, practical and genuinely enjoyable.
Combining serious industry and experience with a relaxed, supportive atmosphere, our sessions are a great way to learn, share ideas and network without the awkward small talk by the snacks table.
We work across the UK with industry associations, schools and training providers, delivering face to face, online and blended learning to suit the way you learn best. And if you’re not quite sure what you need yet, that’s fine too, helping people work that out is also one of our many specialties.
Gemstone Services and supply
And what would we be if we didn't also innovatively supply gemstones and provide expert services too.
We work with jewellers and pawnbrokers to source, repurpose, repolish and supply pre-owned gemstones. Just because a stone has been loved before doesn’t mean it’s lost its sparkle, in fact, recycled gemstones are a brilliant way to offer exceptional pieces at a lower cost while doing your bit for the planet. Every stone is carefully assessed and priced to current trade market value, with detailed images and honest descriptions so there are no surprises (other than rather pleasant ones). With our 30-day refund policy, you can buy with confidence rather than crossed fingers.
Our stone services include gemstone identification, sorting, valuation and stock inventorying, as well as diamond identification, synthetic screening and assessment. As we pride ourselves on being adaptable to the ever changing industry, we are also open to enquiries regarding gemstones that may be on our list. Pretty much, if you have a gemstone issue, we can help you solve it.
How to work with us?
Our clients include independent jewellery retailers, designer makers, goldsmiths, associations, trade bodies, pawnbrokers and auctioneers. The jewellery industry is varied, and so is our experience. While we work with the clients you’d expect, here at Gemmology Rocks we rather like the unexpected too, so if you don’t fit the usual mould, that’s no problem. Luckily for you, we’re not exactly average either.
We’re always happy to arrange a call or in person meeting to chat about your business, your goals, and how we can help you get there. Together, we’ll create a clear plan for how we can work together to achieve success.
If you have any questions or would like to start the conversation, please contact chat@gemmologyrocks.com.
